HOT-WATER HEATING SYSTEM.

Specification of Letters Patent.

Patented Mar. 11.0, 19114.

To all whom it may concern Be it known that I, JOHN F. BARKER, a citizen of the United States of America, residing at Springfield. in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in HotWVater Heating Systems, of which the following is a specification.

This invention relates to improvements in hot-water heating systems, particularly of the type known as the kitchen boiler, which is usually connected with the waterfront of the range.

The present invention is designed to employ this form of boiler in connection with kerosene burners or heaters that are conveniently located below the lower end of the boiler. The oil heaters referred to are known in the market as the blue flame burner, such as are commonly used in oil stoves.

The invention, broadly, consists in placing one or more of these oil or gas burners below the lower end of the boiler and providing means to cause the heated products of combustion therefrom to pass upward and around the exterior surface of the tank and within an inclosing casing that is spaced from the tank a suitable distance. This inclosing casing is preferably provided with a suitable lining of some suitable non-conduetor of heat, as asbestos. A vent is located at the upper end of the jacket to permit the escape of the heated products of combustion. It has been found, in practice, that by inclosing a hot-water tank of the type referred to and employing three of these oil burners, a thirty gallon tank containing water at F. can, in one hours time, be raised to practically 125 F. and that by employing the casing the water will remain hot for several hours, after the flame has been extinguished, the radiation of the heat contained in the water being prevented by the lined jacket already mentioned. The air space, in addition to the lined jacket, also serves to prevent radiation, as it is well known that an air space is an excellent insulator for heat or cold.

Referring to the drawings, Figure 1 is a front elevational view of the completed system, the lower end of the inclosing casing being broken away to show the jacket member that is spaced from the tank, its lining,

and the manner of conducting the heated products of combustion troln the burners upward and around the outer surface of the inclosed tank. This figure also illustrates the position of the oil burners and their connection with the supply. Fig. 2 is a transverse sectional view of Fig. 1 on the line 2-2 and showing the arrangement of the burners with relation to the lower end of the tank. Fig. 3 is a vertical sectional view slwwing a gas-burner for heating a hot water tank, in which the bed-plate for supporting the tank is provided with a single opening and a hood or umbrella plate to conduct or lead away any moisture or water that may collect at the center portion of the tank-the tank employed in this particular instance being a copper one in which the lower end is made convex. in the usual main ner in this type of tank. Fig. lis a vertical sectional view showing a tank in which the lower end is concave and oil burners are employed for heating the water in the tank; this form of bed-plate having several openings to allow the heated products of combustion to pass upward. Fig. 5 is a plan View of the bed-plate proper shown in Fig. 3, illustrating the single opening for the gas-burner and the hood or grip-plate being shown in full lines; the supporting and spacing lugs for the tank being also shown. Fig. 6 is a plan view of the bed-plate shown in F 4 in which oil-burners are employed for heating the tank, and illustrating the several openings through which the heated products of combustion pass. Fig. 7 is a detail view of the hood or umbrella-plate to receive the (.lrippings from the lower end of the tank.

Referring to the drawings in detail.-a designates the usual hot-water tank or kitchen boiler, the lower edge of which is suitably supported on a ring or base-member b. The legs 0, three of which are shown, are secured to the base-plate 6. Located below the lower end of the tank are the oil burners or heaters (Z which consist of the usual blue flame or kerosene oil burners, three of which are shown, as indicated in Fig. 2. The upper ends of the chimneys J of these burners terminate below the lower end of the heater and lit into openings in the base-plate 7), as shown. The heated products of combustion therefrom pass upward directly into contact with the lower end of the tank a, where they spread out, and, inorder to confine these heated products of combustion and cause them to engage the outer surface of the tank a, a jacket of sheet-iron or other material is located outside of and spaced from the tank. This jacket or casing member is designated by the letter 0. The jacket is lined with some suitable non-conductor of heat, as asbestos, that is indicated at f. This jacket and its lining is spaced from the tank a suitable distance, as already stated, which annular space is indicated at g. In this space the heated products of combustion from the burners (Z pass upward and around the outer surface of the tank, as indicated by the arrows shown at it. In order to permit the burned gases to escape from the space 9, a vent-pipe i is provided in the upper end thereof, which pipe may be connected with a chimney or other outlet for the products of combustion.

The oil supply is indicated at j, with which is connected the equalizing tank It and from this extends the supply pipe 1%, permitting the oil to flow into the wick-receiving receptacles n of the burners. A drip-pan 0 is shown for the purpose of receiving any water of condensation that may collect or run back from the tank. Suitable valves in the pipe m for regulating the flow of oil therethrough are shown at p, and the usual wick-adjusting devices are indicated at q. The usual pipe connections for the tank are shown at r, s, t, and a. In order to determine he temperature of the water within the tank a, a thermometer may be provided, the same being shown at o.

Referring now to the construction shown in Fig. 3, in which the tank a is of the usual copper construction, the lower end is made convex, as shown at 10. The lower end of this tank is provided with the usual threaded projection or nipple m by means of which the usual circulating pipe :0 is connected. 3 indicates a hood or umbrella-plate adapted to be screwed or attached to the nipple 5c in order to conduct or carry away any water of condensation that may collect and drip from the convex lower end of the tank. An opening 3 is formed in the bed-plate Z), and over this opening is placed the hood y, as shown in Fig. 3. Cast integral with the bed-plate are the supporting lugs i on which the lower edge of the tank a rests. These lugs have bearing surfaces 4 and a lip 4 to retain the tank in position 011 the bed-plate. These lugs serve the double purpose of supporting the tank and spacing the lower end of the same away from the bed-plate 6, whereby the heated products of combustion from the gas-burner 5 will pass up through the opening 3 into contact with the lower end of the tank and hood At this point, these heated products of combustion are spread out in an even manner and then pass upward into the annular passageway 6 around the tank a, and finally escape by means of the vent-pipe 2' shown in Fig. 1. The bed-plate b is also formed with a channel or annular groove 7 to receive the drippings from the tank a, which are directed into this groove by the hood y, should any occur. After the bedplate 6 becomes heated from the burner 5, these collected drippings will readily evaporate and pass up into the annular passageway 6 along with the heated products of combustion.

Referring to Fig. 4., in which the means for heating the tank are a series of oilburners already referred to, the bed-plate Z) is formed with several inlet openings for the heated products of combustion from the burners (Z. These inlet openings from the oil-burners are shown in Fig. 6 in plan view, four of them being provided, as designated by the numeral 8. In Fig. 4, the tank shown is what is known in the trade as a galvanized iron tank, the bottom portion of which is concave, indicated at 9, and the edge of this tank rests upon the lugs 4, which serve, as already described, to support the tank and space it away from the hed-plate 1), whereby a space or passageway 10 is formed to permit the heated products of combustion to spread out at the lower end of the tank before passing upward into the annular space 11. drippings, or water of condensation, leave the lower end of the tank at the rim portion 12 and drop down into the channel 13. After the bed-plate 6 becomes heated from the burners, this collected moisture is soon evaporated and carried off, as already described. The bed-plate b is formed with a rim b and inside of this rim is located the sheathing or jacket 6. The circulating pipe 14, in the construction shown in Fig. l, passes upward through the center of the bed-plate, as indicated. Between the grooved or depressed portion 7 and the rim or beaded edge is a ledge portion 7 on which the jacket-menr her 6 rests, as shown.

From this construction and the accompanying description, it is evident that a convenient and inexpensive hot-water heating system from kerosene oil, and gas is pro vided. vVhen oil burners are used, it can be installed, in fact, where there is not even city water under pressure, as the tank may be supplied by hand pumps, and, after the water is heated, the lamps extinguished and the heated water drawn off as wanted. Such a system could, of course, be readily installed in country residences.

It should be stated that when a plurality of burners are used, as shown in Figs. 1 and 2, and a, a hood 3 is attached to the In this construction the i pipe 1 to receive any drippings that may run down the circulating pipes at or 14:. The diameter of this hood is such that any drippings will be carried away from the pipe so as to fall into the depressions or grooves in the bed-plate and then evaporated by the heat from the burners.

What I claim is:

1. In a hot-water heating system, the combination with a tank for containing the water to be heated, of a bed-plate member for supporting the tank and provided with means to space the lower end of the tank from said member, the member having an opening in the central bottom portion, a j acket-member surrounding and spaced from the tank to atl'ord an annular passageway for the heated products of combustion to pass up and around the tank, said passageway communicating with the space below the lower end of the tank, a burner arranged below the opening in the bed-plate to perunit the products of combustion to pass up ward into the space below the lower end of the tank, and to cause the heated products of combustion to spread out in an even manner before they pass upward into the annular space around the tank, and an annular groove formed in. the bed-plate and about the burner opening to receive and retain any drippings from the tank that may occur whereby when the bed-plate becomes heated the drippings will be evaporated and pass upward with the heated products of combustion, as described.
